Try this:
a = Foreign("IRX", "C");
a1 = Foreign("TYX","C");
a2 = ema(a/a1,20);
a3 = ema(a2,13);
Then plot whichever EMA you want using the plot function

Have the following that someone did in another charting software package. Would like to be able to do this in AB if someone can help me out along the way here
This was originally constructed in Metastock, using the 13 week treasury yield (IRX) divided
by the 30 year treasury yield (TYX) as the base security. A 21 ema is applied, the base security is no longer displayed. Then the other moving average is a 13 ema of the 21 ema.
Thank you for any help here
